What should parents pay attention to when their children are late in tooth replacement? Many parents mistakenly believe that their children are late in tooth replacement due to calcium deficiency or lack of trace elements. However, the early or late tooth replacement has little to do with calcium deficiency, so don’t blindly take calcium supplements. If you are really worried about your child’s calcium deficiency, you can take your child to a professional hospital for a trace element or calcium deficiency test, and then decide whether to supplement calcium. In addition, many babies have a genetic predisposition to late tooth replacement. You can determine whether your baby has a problem with early or late tooth replacement based on the parents’ early or late tooth replacement. What’s more, some babies do go beyond the budding time range, by a lot, even beyond 3 to 6 months! So it is still recommended that parents bring their children to the dentist for an examination to determine if there are other causes! What is the cause of baby’s teeth turning black? Baby’s teeth are not black at the beginning, after 2 years old, the surface of the teeth slowly become black, analyze their possibilities, there are two possibilities 1, is the existence of the black surface of the teeth, may be due to the pigmentation of the pigmentation due to brush teeth not clean, this, through the scaling can be dealt with. 2, the possibility is that the caries is a little deeper, not only shallow on the surface.

Why do babies have tooth decay even if they don’t eat candy? In fact, it is not a single candy that is called sugar. In fact, sugar is a big category, including milk and food that contain sugar, such as starch, which is a form of polysaccharide. Sometimes starch is more prone to tooth decay than candy because it adheres to the surface of teeth more easily. After adhering to it, it can decompose and produce sugars that bacteria like more, which can easily cause tooth decay. Therefore, not only should you control your child’s candy intake, but you should also pay attention to oral hygiene maintenance and rinse or brush your teeth after eating staple foods.

Of course, some children may be a little earlier or a little later than this range, but these are not particularly abnormal, just early or late.
